What Are Diagnostic Trouble Codes (DTC)? The codes produced from the OBD are known as fault codes or diagnostic trouble codes. OBD codes identify a problem within the broader system, such as the chassis, body, powertrain or network, whereas a DTC code addresses an issue in a specific area...
PDU Type: PDU type. Maximum Area Address: maximum number of area addresses supported by an IS-IS area. Currently, this field has a fixed value of 0, indicating that a maximum of three area addresses are supported. TLV: Type/Length/Value. The TLVs contained in PDUs of different types are...
Hence, the voltage across the inductor becomes zero. Thus, as far as d.c. quantities are considered, in steady-state, the inductor acts as a short circuit. Current Through an Inductor We can express current through an inductor in terms of voltage developed across it as In the above ...
A circuit breaker is defined as a switching device that can be operated manually or automatically for controlling and protecting anelectrical power system. It consists of two main contacts: a fixed contact and a moving contact. The contacts arenormallyclosed and allowcurrentto flow through the circ...
(3) Before connecting the cable, the tester must note that each phase of the cable is connected to the ground with a short-circuit wire, and one end of the short cable must be grounded, and the other end must be connected to the discharge of each phase of the cable. Other electrical...
often some desirable and others undesirable. The filter circuits are used for equalization; enhancement or suppression of specific frequencies to ensure quality audio. In hi-res quality audio, a crossover network, type of filter circuit is used in dividing audio signals into distinct frequency bands...
Proper fault diagnosis allows targeted and rapid rework. There are three common fixture types used in ICT. Each has particular pros and cons: Bed of Nails Consists of an array of spring-loaded “nails” or “pins” that make electrical contact with test points on the board. Very common fixt...
What to consider before buying a tactical flashlight? If you are looking for the best tactical flashlight at an affordable price, then read this review
Once the faulty diodes are identified, a technician can simply replace them, and the scoreboard should work like normal again. Final Thoughts Though small and simple, the diode is an essential part of modern electrical systems. By controlling the flow and direction of current, diodes enable count...
A substance that can conduct electricity is called theconductorand a substance that cannot conduct electricity is known as the insulator. Semiconductors have properties that sit between the conductor and insulator. Adiode, integrated circuit (IC) andtransistorare all made from semiconductors. ...
